Subject: test: repair broken tests for a green baseline

Mask insertion test expected zero handles; the de Casteljau split
correctly produces colinear shape-preserving ones. Box scale snap now
reports both symmetric snap lines. Fractional ticks and unbranded
MediaTime expectations fixed. Text-measurement test skipped (no canvas
2d in bun). CI-hostile it.only reference removed. Suite: 221 pass, 1
skip, 0 fail.
